After the magnitude 8.3 earthquake in Mexico last week, an acquaintance of mine was fretting about how these natural disasters couldn’t be a simple coincidence.

Of course, that acquaintance was referring to the apparently large number of violent systems in the South Atlantic this hurricane season in combination with an earthquake. I’m not sure what these phenomena have to do with each other. How are weather and geology supposed to be connected? Perhaps in the very long term, on the scale of eons. But over days or hours? Not likely.

Humans have a propensity to see causality and correlations where there is just coincidence. Most things happen for no reason at all. It’s easy to see patterns where there are none, especially in nature. If you see linkages where there are none, you can drive yourself crazy with anxiety and paranoia. Things happen. Sometimes they bunch up in time and place. Other times they are more or less spread out.

The trick to being prepared isn’t so much to predict specific causes or events, it’s to prepare for generic outcomes and effects. If you’re in a hurricane or seismic zone, you can’t predict when or where events will occur, but you know that they will occur with a certain frequency and power. For instance, every decade or two, there is a major hurricane in your zone. Every year there is at least a major tropical storm. Geological risks are much harder to characterize, but if you are in high-risk seismic region, then you have to prepare for the worst case.

Of course, preparedness and resiliency are largely a function of wealth. Storms, earthquakes and other natural events are a lot costlier in wealthy regions, but relatively less destructive of life and limb. In poor regions, the relationship is inverted; there are many more deaths and the destruction, although extensive, costs much less. However, the time to rebuild and recover are a direct function of wealth. The greater the capital resources, the faster and easier it is to absorb the costs of reconstruction and resiliency.

These factors also play into the perceptions of coincidence, causality and correlation. We must keep things in perspective when assessing probabilities and impacts. Human destruction is greater in poor countries and increases toward the past. Material destruction was less in the past and is continually increasing. This isn’t because of some connection between events. Rather, it comes from the increased investments in infrastructure, housing, and transportation networks. What was the damage along the Gulf Coast or in Florida prior to people building houses right on the water?
